Parsing lnk files in windows

[raysod]

Does anyone have any experience parsing Windows *.lnk files. I've tried reading them into a byte array but when I evaluate the array byte by byte the 32 bit sequences appear to vary from little endian to big endian. I'm trying to map a lnk file based on the file specs found on Microsoft.com ([MS-SHLLINK]: Shell Link (.LNK) Binary File Format). Please let me know if I'm reading byte output incorrectly or if I'm just missing something. FYI, I'm using an Intel(R) Core(TM)2 Duo CPU X86 processor

See code and output below. Thanks

package com.aMAEze.utilities;

code
import java.util.*;
import javax.swing.*;
import java.io.*;



public class ParseLnkFile
{

public ParseLnkFile(File file)
{
if (file.exists())
{
try
{
loadFile(file);
}
catch (IOException ioe)
{
}
}

for (int ii = 0; ii < bytearray.length ; ii++)
{
System.out.print(Integer.parseInt(new String(bytearray,ii,1),16) + " " );
if ((ii >= 8) && ((ii % 8) ==0)){System.out.print("\n");};

}
}


public ParseLnkFile(String filepath)
{
File file = new File(filepath);
if (file.exists())
{
try
{
loadFile(file);
}
catch (IOException ioe)
{

}


for (int ii = 0; ii < bytearray.length ; ii++)
{
System.out.print(Integer.toString(bytearray[ii],16) + " ");

if ((ii == 7) || ((ii > 8) && (ii % 8) == 0)){System.out.print("\n");};

}

}
}

private byte[] bytearray;

private void loadFile(File file) throws IOException
{
FileInputStream fin = new FileInputStream(file);
ByteArrayOutputStream bout = new ByteArrayOutputStream();

byte[] buff = new byte[256];
int offset = 0;
int numRead = 0;

while (true)
{
int n = fin.read(buff);
if (n == -1){break;};
bout.write(buff,0,n);
}


fin.close();
bytearray = bout.toByteArray();


}
}



output **notice the first 32 bits appear lttle endian according to the specs. 4c 0 0 0 s/b 000 4c as is the second 32 bit segment. Then look at the 4th 32 bit segment and it appears to be big endian -40 0 0 0 appears -40 0 0 0.

Does anyone have any experience parsing Windows *.lnk files.

I tried it once (in VFP, not Java) but gave up in disgust when I discovered that different Windows versions have differing .lnk formats.

My purpose was different -- I hoped to create the .lnk from my program without going through the wsshell.script (?) ActiveX.

Thanks anyway. Do you have any experience with binary files? Does it make sense that the 32 bit sequences seem to go from little to big endian?
